Non-Fusee Variant?

Hi,

Great website!

I have just obtained a 1930's gledhill brook time recorder, however although the movement looks like the usual movement, this movement does not have a fusee!

The power is from a (now broken) OPEN spring. This appears unusual in a gledhill brook clock. The broken spring has appeared to have damaged some teeth.

So I was just wondering if anyone else has seen this variant?

Best wishes

Derek
